Plug Power Inc. completed a private offering of $431.25 million of 6.75% Convertible Senior Notes due 2033. The notes were sold at 95% of face value, giving the company net proceeds of about $399.4 million.
The notes bear 6.75% interest, paid twice a year, and mature on December 1, 2033, with holders able to convert after a specified date into cash, common stock, or a combination, at the company’s election. The initial conversion rate is 333.3333 shares per $1,000 of notes, equal to an initial conversion price of roughly $3.00 per share, a 40% premium to the $2.14 stock price on November 18, 2025. The company also discloses an initial maximum conversion rate of 467.2897 shares per $1,000, allowing up to 201,518,683 shares to be issued if fully converted.
Plug Power used approximately $245.7 million of the proceeds to fully repay its 15.00% secured debentures, including accrued interest and a termination fee, and about $153.9 million to repurchase $138.0 million principal of its 7.00% convertible notes due 2026. Remaining funds are earmarked for working capital and general corporate purposes.
Plug Power Inc. has called a virtual special meeting on January 15, 2026 for stockholders to vote on two major charter changes and a possible adjournment. The first proposal would amend the charter so that certain future amendments, including changes to authorized shares and reverse stock splits, can be approved by a majority of votes cast, aligning the company’s standard with Section 242(d)(2) of Delaware law.
The second proposal would double the company’s authorized common stock from 1,500,000,000 to 3,000,000,000 shares. Plug Power states it has less than 0.4% of its authorized common stock available and highlights contractual obligations tied to warrants to purchase 185,430,464 shares issued on October 9, 2025 and $375.0 million of 6.75% convertible senior notes due 2033 issued on November 21, 2025. The board prefers direct authorization of more shares over using a previously approved reverse stock split and is also seeking authority to adjourn the meeting to solicit additional proxies if needed.
